How Noisy is your 09 WRX Engine?

I notice quite a bit of rattle/knock type sound in first gear. This happens mainly under slight acceleration. If you hammer it it seems to smooth right out. I don't know if it's just the normal subbie sound or if its something to be concerned about. I am at 56K and it has always made this sound. It may just be my mind but it seems to be a little louder now.

Has anyone experienced this noise from day one?

Here is a quick video. You can hear the rattle/knock sound as I cruise in 1st gear. This clears up when you get on it.

Sounds like a heat shield rattling at the 19 second mark. Is that the sound you're talking about?

If so, it sounds almost like the turbo heat shield.

I agree with Chris about the heat shield rattle. Other than that it sounds normal to me.

Listen between 2 and 3 seconds. The sound i am hearing is most pretty loud at that point. This may just be a normal sound, I just have it in my head that my rod bearing are gong to go. I know I am not in that date range, but still. I would think they would have let go by now though....
